Portuguese winger Nani may have signed a new deal with Manchester United as recently as September, but according to the player's agent, it is very likely the 27-year old speedster will be leaving the club at the end of this year.

Nani is a very important player and at this time the only thing I can say is that he is likely to leave Manchester. The problem for Fiorentina and other Italian clubs is the player's salary. But we will evaluate all bids.

Our relationship with United is great. Fiorentina have to speak with Manchester United about Anderson and maybe there will be an opportunity to talk about Nani too.

Fiorentina currently loan Brazilian midfielder Anderson from the Red Devils, and with United scouting La Viola's Juan Cuadrado, as reported by The Daily Mail's Simon Jones, both Anderson and Nani could potentially be used in a deal for the talented Colombian.

David Moyes was hell-bent on resigning Nani earlier this season, as it appeared the Portuguese winger would become part of the foundation on which the coach wished to build his team. However, issues with fitness and form have seen the player make only five league starts all season.

Transfer speculation has surrounded Nani for several seasons now, and according to Sky Sports, Fiorentina were one of the clubs interested in the player's services in January. No deal materialised, but La Viola seem to have rekindled their interest ahead of this summer's transfer window.

The main issue with any move for Nani would be the player's salary, which Metro's Jamie Sanderson reports is £95,000 per week, including "lucrative bonuses." The financial crisis has hit Italian football hard, and as reported by Forzaitalianfootball.com, only a handful of Serie A clubs are actually profitable.

Nani would almost certainly have to sacrifice part of his salary to make the move to Italy, and given the player only recently had his wages increased with United, it might be hard for the winger to agree to a pay-cut just one year later.

As shared by Mr Transfer News, this has been a problem in the past:

Nani likely to leave Manchester United this summer. Only problem that has stopped this in previous transfer window's, is his wage demand.

Nani hasn't been an impact player for United in quite some time now, and clubs won't be looking to spend a king's ransom on a player who hasn't shown any signs of improving on the five starts we've seen so far in the 2013-14 season.
